An image matching method, and an arithmetic system for executing image matching processing

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to image matching processing for performing positional alignment of a pattern on design data and a pattern on an image, and more particularly to image matching processing using a model built by machine learning. This method converts a designated CAD pattern on design data into a CAD image 301, inputs the CAD image 301 into a model built by machine learning, and executes calculations according to an algorithm defined by the model, A pseudo image 321 is output from the model, and a pattern having a shape closest to that of the CAD pattern 322 on the pseudo image 321 is selected from among a plurality of patterns on the image generated by the image generating apparatus 100 . decide
